Classification of Matter, Mixing & Dissolving

Pure substances can be made up of:

• Elements and compounds

• Solutions and mechanical mixtures

• Compounds and solutions

• Elements and mechanical mixtures

Mixtures can be made up of:

• Elements and compounds

• Solutions and mechanical mixtures

• Compounds and solutions

• Elements and mechanical mixtures

Solutions are:

• Homogeneous; you CAN tell they're multiple substance mixed together

• Homogeneous; you CANNOT tell they're multiple substances mixed together

• Heterogeneous; you CAN tell they're multiple substance mixed together

• Heterogeneous; you CANNOT tell they're multiple substances mixed together
